Jackie, the famous bald eagle who lives in the San Bernardino National Forest, laid her second egg of the year over the weekend.

The bald eagle mother and father, Shadow, have been taking turns sitting on the nest.

"They are both very diligent about turning the eggs each time they up to change position," according to the organization's Facebook page, which added that they've been in an apparent nesting phase, each taking turns bringing a variety of twigs and sticks to place around the eggs.

The incubation period for bald eagle chicks usually takes about 35 days after the first egg is laid, according to officials.
